List of NHL game sevens

In the National Hockey League (NHL), a game seven is the final game in a best-of-seven series in the Stanley Cup playoffs. Based on the playoffs format arrangement, it is played in the venue of the team holding home-ice advantage for the series. The necessity of a game seven cannot be known until the outcome of game six is determined, assuming that a series reaches the sixth contest. In other words, game seven is the only one in a best-of-seven series that cannot be guaranteed more than one game in advance.

The Stanley Cup Finals first employed the best-of-seven format in 1939. The league's semifinals also used the best-of-seven format beginning that same year, as well as the quarterfinal round that was added in 1968. Beginning in 1982, the playoff format was changed from semifinals and quarterfinals, to conference finals and division finals, respectively. A division semifinal round was also added in 1982, but did not begin to use the best-of-seven format until 1987. Starting in 1994, the division final and division semifinal rounds became the conference semifinal and conference quarterfinal rounds, respectively. Beginning with 2014, these rounds were renamed to simply the "first" and "second" rounds.

Since instituting the best-of-seven format for the 1939 Stanley Cup playoffs, 166 game sevens have been played. Of those, 69 have been won by the road team. There have been 19 seasons in which no game sevens were played: 1940, 1943, 1944, 1946, 1947, 1948, 1951, 1956, 1957, 1958, 1960, 1961, 1962, 1963, 1966, 1967, 1970, 1973, and 1977. In 2005, no playoffs were held due to the 2004–05 NHL lockout. Two active NHL franchises have never played in a game seven: the Columbus Blue Jackets, and the current Winnipeg Jets franchise which relocated from Atlanta prior to the 2011–12 season. The 1994, 2011, and 2014 playoffs hold the record for most game sevens played, with seven out of a possible fifteen. The Boston Bruins and Detroit Red Wings have played in 25 game sevens in each franchise's history, the most of any team in NHL history. The Detroit Red Wings and Montreal Canadiens have won 14 game sevens each, the most of any teams in NHL history. The Bruins and Los Angeles Kings hold the record for most game sevens played in a single season, having played three in 2011 and 2014, respectively.
